Another classic book on soul-winning is
Evangelism Explosion, by James Kennedy, a Presbyterian. This book is copyrighted 1970, but by the 6th edition (what I have) the very next year it had sold 105,000. All in all it is a good book to have on the subject, especially for a pastor, since it is designed to be used in training believers to win souls.
The basic design of the book is based on complete personal evangelism experiences Dr. Kennedy has written out, with many helps for different problems and questions the prospect has. There are also chapters on "The Proper Use of Testimony," "Handling Objections," "Do's and Don'ts," and so forth, with an excellent follow-up program in the last chapter.
One interesting thing is that Ray Comfort may have been influenced strongly by this book, which is included in Comfort's "Suggested Reading" list at the end of Hell's Best Kept Secret" (along with some other books that disagree completely with Comfort's method--go figure
). The reason I say that is that Comfort uses "Four principles of selling" in his book (Ch. 8) and Kennedy uses the "Five Laws of Selling" (pp. 58-60 in his book). To be fair, though, the two sets of principles are somewhat different.
Again, Kennedy uses the law somewhat, though not nearly as much as Comfort. And Kennedy does not require the use of the law in his method, as does Comfort.
I do have one caveat to recommending Kennedy's book, and that is that openly requires the prospect to accept Jesus as Lord as part of the deal (p. 53), long before John MacArthur wrote about the subject--but that will be all to the good for some of you.
